Title: Comparator
Inventor: TAKAHASHI MASAHARU
IPC: H03K5/08
Filed: 1988-09-05
Abstract: PURPOSE:To expand the range of the input potential of a comparator by providing a resistance element which inputs an input voltage in a divided state to differential input stages of the comparator and inputting the input potential to the differential input stages by dividing the input potential by means of resistances. CONSTITUTION:Resistances 3, 4 and 5, 6 which respectively divide input signal potential VIN<+> and VIN<-> and drop a voltage are provided to differential input stages of a comparator 7 provided with power sources V1 and V2. The resistances 3-6 drops the input potential VIN<+> and VIN<-> across terminals 1 and 2 and input the dropped voltage to the comparator 7. Therefore, when the resistances 3-6 are adjusted, the input potential VIN<+> and VIN<-> can be made higher than the positive-side power supply voltage VDD of a positive power supply terminal 9a and negative-side power supply voltage VSS of a negative power supply terminal 9b and the input signal range can be expanded.

Filed: 1983-11-24
Abstract: PURPOSE:To prevent the generation of conductive rusts causing discoloration in solder and hindrances in the function as electronic components by a method wherein outer lead terminals and the solder are completely surrounded by the base metallic layer and the surface metallic layer.

Title: Thin tube low pressure mercury discharge lamp
Inventor: KAWASUMI KENICHI
IPC: H01J61/24
Filed: 1985-10-07
Abstract: PURPOSE:To uniform the brightness of a thin tube low pressure mercury discharge lamp along the length of the tube by controlling the mercury vapor pressure at the position for dividing the length of a light emission tube equally. CONSTITUTION:A light emission tube 1 of a thin tube low pressure mercury discharge lamp comprising a thin tube having the inner diameter of 6mm and the tube length of 850mm is bent to be in parallel in same plane thus to form the sections A', B', C' and D' where a branch tube 6 for controlling the mercury vapor pressure is coupled to the vicinity of the border between the sections B' and C' while the tip section of the tube 6 is secured in the base metal 4. When there is no tube 6, the temperature at the tube end section is low to collect mercury vapor thus to cause uneven brightness but the temperature at the tube end section can be controlled by means of the tube 6. Consequently, uniformity of the mercury vapor density distribution can be maintained in the tube resulting in uniform distribution of the brightness along the length of tube.

Title: Manual operation device for elevator hoist
Inventor: MITSUI ATSUSHI
IPC: B66B5/00
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To manually operate a hoist from outside of a hoistway and easily prevent interference with a car, a balance weight, and other hoistway apparatus, by providing a rotation wire for manually rotating a pulley fixed to a rotation shaft of the hoist. SOLUTION: For manually operating a hoist 1, a release wire 7b of a release flexible cable 7 is pulled from outside of hoistway to oscillate a brake release lever 6 to release a brake device 5. When load on a car almost balances with weight of a balance weight, an operation lever 15 is rotated to rotate pulley 9. When the operation lever 15 is rotated, the other end 10d of a rotation wire 10b is pulled out from a rotation tube 10a, and the rotation wire 10b moves against a tensile spring 12. Because the release operation of the brake device 5 and a rotation operation of a rotation shaft 4 are performed using flexible cables 7, 10 with high freedom for layout, interference with a car or others can be prevented.

Title: Method for detecting fiber-raising direction of pile fabric
Inventor: HIRAOKA OSAMU
IPC: D06H3/00
Filed: 1990-08-22
Abstract: PURPOSE:To detect the fiber-raising direction of a pile yarn from the vertical displacement of a plate probe having a proper area by contacting the probe with the planted yarn face of a pile fabric under pressure and parallelly moving the probe relative to the fabric. CONSTITUTION:An anvil 5 is made to contact with the base cloth side of a pile fabric and a plate probe 6 with the pile yarn side of the fabric. A spindle operation lever 7 is lowered and the reading of a dial gauge 3 is taken as the standard when the pressure of the probe 6 is balanced with the elastic repulsive force of the pile yarn. The device is moved in a definite direction at a constant speed while keeping the above state. When the moving direction coincides with the raised direction, the pile yarn is fallen with the probe 6 to decrease the thickness of the cloth and the reading of the dial gauge is deflected to minus side from the above standard. On the contrary, the pile yarn is raised when the moving direction is opposite to the raising direction and the cloth thickness is increased to deflect the dial to the plus side. The raising direction can accurately be detected by this process using a commercially available thickness gauge with slight modification.

Title: Liquid container
Inventor: KUBO NAOFUMI
IPC: B65D77/06
Filed: 1994-09-19
Abstract: PURPOSE: To enable an cap-closing of a liquid container having a thin wall placed in the inside of a corrugated cardboard case, using a force cap by a method wherein a support stepped part is provided in a position somewhat below the upper edge of the inner peripheral wall of the corrugated cardboard case, a support board having an engaging hole engageable with the engaging face of the outer periphery of a mouth part and its outer periphery is supported on the support stepped part. CONSTITUTION: When a force cap 11 is placed on the mouth part 5 of the inner thin wall container 3 of a corrugated cardboard case 2, and is pressed thereagainst after the container is filled with liquid, since the resulting pressing force exerted on a support board 14 by engagement of the engaging face 9 of the mouth part 5 with the support board 14 is supported on the corrugated cardboard case 2 via a support stepped part 13, the engaging outer peripheral edge of the cap 11 is forced into engagement with the engaging face 9 by the support force resisting to the pressing force of the cap 11, whereby the container can be closed with the cap 11.  Therefore, although a liquid container 1 has the thin wall container 3 placed on the inside of the corrugated cardboard case 2, it can be closed with the force cap 11 and can be filled with liquid by using the conventional filling equipment as it is.
